Avascular Necrosis

Avascular necrosis, most commonly seen the femoral head, results when the vascular supply of the bone is interrupted leading to bone death. Many times, the necrosis is idiopathic, asymptomatic, and the cause of it is still not clearly understood by the medical community. However, early detection is important in order to reduce the collapse of the articular surface which leads to degeneration of the hip. In very severe cases, a joint replacement may need to be done in order to repair the dead area. This condition is serious and should be referred out to a physician.
